JSTOR offers high-quality, interdisciplinary content to support scholarship and teaching. The JSTOR digital archive includes more than 1,500 leading academic journals in the humanities, social sciences, and sciences, as well as select monographs and other materials valuable for academic work such as Hebrew language journals. The entire back runs of journals (from volume 1, issue 1) are always included, and in 2010 JSTOR expanded its vast collection of archival content to include the most recent issues of select academic journals through the Current Scholarship Program.

Additional collections include valuable primary source content. The entire corpus is full-text searchable, offers search term highlighting, includes high-quality images, and is interlinked by millions of citations and references. The content is expanded continuously with an emphasis on international publications as well as pamphlets, images, and manuscripts from libraries, societies, and museums.

JSTOR content is placed in collections, and institutions are able to choose which collections best serve their needs.
